Dynamics and entanglement near quantum phase transitionsMy research will uncover and characterize novel states of quantum matter, especially those emerging near phase transitions. Of particular interest are transitions that are driven by quantum fluctuations, in contrast to the familiar ones where thermal effects dominate. These quantum phase transitions are not only of fundamental interest, but also of practical relevance as they can, for instance, shed light on high temperature superconductivity. I will study their dynamical and quantum entanglement properties. My interdisciplinary approach will combine analytical and numerical tools from condensed matter with insights from quantum information and string theory.

量子相变的动力学和纠缠将发现并表征量子物质的新型状态，尤其是那些近相跃迁的状态。特别令人感兴趣的是由量子波动驱动的过渡，与热效应占主导地位的熟悉的转变相反。这些量子相变不仅具有基本兴趣，而且具有实际相关性，例如，阐明了高温超导性。我将研究它们的动力学和量子纠缠特性。我的跨学科方法将结合凝结物质中的分析和数值工具和量子信息和弦理论的见解。
